Twang!!

This 1965 musical by Lionel Bart was a notorious flop.

Twang!! is a musical with music and lyrics written by Lionel Bart and a book by Bart and Harvey Orkin, an American theatrical agent and former writer for The Phil Silvers Show. When production faced issues, American writer Burt Shevelove was called on to help fix the book. The piece, a spoof of the character and legend of Robin Hood, was a disastrous box-office failure and cost Bart his personal fortune.
